Ch 19 - Level Flight And Climb Flashcards
1
Q
Pitch Angle
A
AoA + Flight Path Angle
2
Q
AoA
A
The angle between the flight path angle and the longitudinal axis
3
Q
Flight Path Angle
A
The angle between the Horizontal axis and the Relative airflow
4
Q
Load Force
A
= Lift / Weight
5
Q
Lift equation in a steady climb
A
L = W cos Gamma
6
Q
Flight Path Angle Equation
A
Sin Gamma = (Thrust - Drag) / Weight
7
Q
Vx
A
Climbing angle
Will increase with a heavier aircraft
Will decrease with a dirty configuration
Turbojet = Greatest excess thrust which is the same as Vmd
- Close to stall speed
8
Q
Effect of Altitude on Flight Path
A
thrust decreases with altitude so the climb angle has to reduce. So as you climb you end to continually decrease the pitch to maintain a constant AoA
9
Q
Climb Gradient Equation
A
%G = (T-D)/W X100
